摘要： A propeller housing for a marine vehicle is provided which incorporates an improved locking structure for maintaining the propeller assembly on the drive shaft of the marine vehicle. The locking structure includes a spider washer having first and second ends and an aperture therebetween for receiving the propeller shaft therethrough. The spacer element includes a nose portion adjacent the first end thereof. A locking washer has an opening for receiving the nose portion of the spacer element therethrough and an outer periphery which maintains a propeller assembly on the propeller shaft. A locking element is mountable on the threaded end of the propeller shaft for retaining the spider washer thereon.

摘要： An article and a method for improving an article that results in a reduction or elimination of damage due to fretting from contact of similar metals. The invention specifically reduces wear-related fretting between titanium alloy parts by lowering the stresses between mating parts. An aluminum bronze coating is applied to one of the parts. The aluminum bronze coating provides an improvement over prior art coatings in reducing coefficient of friction between the parts. Additionally, the cumulative stresses at the surface of the parts is reduced by a dual intensity peening treatment. This involves a first peening operation using large peening media that provides a compressive stress to the required depth. This first peening operation is followed by a second peening operation that provides additional compressive stresses closer to the dovetail surface. The combined metallurgical and mechanical improvement results in a system with less susceptibility to fretting damage and corresponding improved fatigue resistance.
摘要翻译：一种用于改善制品的制品和方法，其导致由于类似金属的接触而导致的微小损伤的减少或消除。本发明通过降低配合部件之间的应力来具体地减少钛合金部件之间的磨损相关的微动。将铝青铜涂层施加到其中一个部件。铝青铜涂层在减少部件之间的摩擦系数方面提供了优于现有技术的涂层。另外，通过双重强度喷丸处理减少了部件表面的累积应力。这涉及使用提供压缩应力到所需深度的大型喷丸介质的第一次喷丸操作。该第一喷丸操作之后是第二喷丸操作，其提供更靠近燕尾表面的附加压缩应力。组合的冶金和机械改进导致系统对微动损坏的敏感性较小并且相应地改善的耐疲劳性。

摘要： An apparatus for axially retaining rotor blades to an annular radially extending disk having a recess and a flange. An annular retaining ring is disposed in the recess and includes an axially extending lip and an axially outer side forming an annular bevel surface along a radially outer edge. A retaining plate having an axially extending base, a radially extending outward arm and a radially extending inward leg having an annular bevel surface along an axially inner, radially inner edge is affixed to the disk and the leg cooperates with the lip of the ring. Wherein, the bevel surfaces of the retaining plate and retaining ring are arranged outwardly opposite to one another so that the bevel surfaces are radially compressed along each other as the base slidably engages with the recess walls.

摘要： A ceiling fan structure including a housing, a motor casing, a fixing disc and multiple vanes. A motor is installed in the housing and enclosed in the motor casing. The motor casing is formed with multiple thread holes on a periphery of bottom face of the motor casing. Multiple vanes are pivotally disposed on bottom side of the fixing disc via vane brackets. The fixing disc is formed with multiple through holes corresponding to the thread holes. A bolt is passed through each through hole for locking the motor casing with the fixing disc and spacing the motor casing from the fixing disc by a certain distance, A spring is fitted on each bolt within the distance for absorbing swinging force exerted onto the vanes during rotation of the ceiling fan.
